Active inductors Microwave circuits Microwave devices MMICs Optical control Optical devices Optical feedback Optical filters Optical mixing Stimulated emission
An optically controlled MMIC compatible active inductor is demonstrated. The device is realized by a MESFET based circuit configuration which exhibits a shunt inductive characteristic which may be tuned by direct illumination of one of the circuit's MESFETs. The optically tuned active inductor may then be incorporated into a variety of microwave circuits whose performance may be controlled via direct optical illumination of the active inductor.
